Hello Charles1Dad,
First, thank you for all the helpful comments. I believe I will likely go Coincident speakers, or one of the following: Dadaedlus, Devore Orangutan O96/93, Line Magnetic 755 Field Coil or something else like these. I currently own Tekton 4.5, Tekton M-Lore, Tekton Lore plus Infinity Prelude Composition. The Infinity is actually a good speaker from around the year 2000, at a cost of about $3,495. It is 96db efficient, 6 Ohm, with a built-in amp that drives the 12 inch solidly to 25 Hz. This speaker sounds really nice with the Cary 300SEI, even better with the Cary V12 SET, run at 50 watts Triode. The tubes I have run in the V12 include KT66, El34s, as well as NOS Reflector 6n3ces.
I am listening to the Dynamo 34SE hooked up to the Tekton M-Lore, 95db, 8 Ohm, clean 38Hz. Transport is a Sony SACD S9000ES connected to a Eastern Electric MiniMax DAC with Shuguang Black Treasure 12au7 tube, older Custom Power Cords, MIT digital cable, Silnote interconnect and PS Audio Statement speaker cables. Somehow, it all meshes; and my 16x14 office is a great listening room, never a problem, easy set-up.
